[PATCH] MXC: set GPIO IRQ handler

[John Ogness <john.ogness@linutronix.de>]

The irq chip function gpio_set_irq_type() correctly sets the i.MX
registers but does not set the irq handler. This means that all
gpio-based irq's are handled with handle_edge_irq().

This patch corrects this by also setting the appropriate handler.

This patch is against 2.6.32-rc8.
